Installing MySQL
Download MySQL 4.0.17 at:
http://www.mysql.com/get/Downloads/MySQL-4.0/mysql-4.0.17-win.zip/from/http://mysql.orst.edu/
Unzip “mysql-4.0.1-win.zip” and execute “setup.exe”
Choose a directory, select typical install options.
Once installation is complete, go to your autoexec.bat file and put: SET MYSQL_HOME=C:\mysql SET PATH =%MYSQL_HOME%\bin;%PATH% -where “C:\mysql” is the location where you installed mysql.
Once mysql is installed, and your variables are setup, you need to install the mysql server “service”. To do this type: C:\mysql\bin> mysqld --install //installs the service C:\mysql\bin> NET START MYSQL //start the mysql server
Connecting to the MySQL Server
• SYNTAX: mysql -h host -u user -p << EXAMPLE >> C:\mysql\bin> mysql –h localhost –u root –p
NOTE: THE DEFAULT PASSWORD FOR ROOT IS BLANK !!!
Changing “ROOT” password
GET USER FIRST: C:\mysql\bin> mysql -u root mysql CHANGE PASSWORD SYNTAX:
mysql> UPDATE user SET Password=PASSWORD('new_password') WHERE user='root'; mysql> FLUSH PRIVILEGES; DON NOT FORGET THE
“ ; “ semi-colon
Interfacing with MySQL Server
• The command-line is too cumbersome, we need a GUI!! • Enter the MySQL Control Center • Download at: http://www.mysql.com/get/Downloads/MySQLCC/mysqlcc0.9.4-win32.zip/from/http://mysql.orst.edu/ • Unzip mysqlcc-0.9.4-win32.zip and install:
• Open Control Center and Register your MySQL Server
• • • •
NAME: Any name you want HOST: DNS NAME OR IP-ADDRESS of MySQL SERVER USERNAME: Usually root PASSWORD: Leave blank, UNLESS you changed it.
Hack the GUI on your own time!
Interfacing with Java: Important Points
• Use ConnectorJ “JDBC Driver” • Include mysql-connector-java-3.0.10-stable-bin.jar in your java project • Import com.mysql.jdbc.Driver; • Get to know the java.sql.* Package! Understand “DriverManager” and its relationship with a “Connection”. OTHER CLASSES OF USE: ResultSet - The format Data is retrieved from a Database. Statement - Used to query a Database for a ResultSet. CallStatement - Execute a StoredProcedure in the database to obtain a ResultSet.
